Thalamus

Front 2

What structure forms the floor of the third ventricle?

Back 2

Hypothalamus

Front 3

What structures comprise the Limbic System?

Back 3

Hippocampus
Fornix
Amygdala
Cingulate Cortex

Front 4

If you couldn't see the hypothalamus on a coronal section, what structure of the Limbic System would you expect NOT to see?

Back 4

Amygdala

Front 5

What gross changes in the brain can you expect to see in a patient with Alzheimer's Disease?

Back 5

Deteriorated cortex, enlarged ventricles (deteriorated areas fill with CSF)

Front 6

What structures comprise the basal ganglia?

Back 6

Globus Pallidus
Caudate
Putamen

Front 7

What is the role of the basal ganglia? What division of the nervous system does it fall under?

Back 7

Role: Motor control
Division: Telencephalon

Front 8

What structures in the Basal Ganglia are affected by Parkinson's Disease?

Back 8

Caudate and Putamen (these are where dopamine secreted by SN in midbrain acts)

Front 9

What structure comprises the lateral wall of the lateral ventrical?

Back 9

Caudate (follows it from anterior horn to temporal horn)
